LINER FOR CENTRIFUGAL CREAM-SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 635,488, dated October 24, 1899.

Application filed August 1, 1898. Serial No. 687,4:6'7. (No model.)

To all whom it ntay concern.-

Be it known that I, EDWIN J. KNEELAND, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain Improve ments in Milk-Quieting Devices for Centrifugal Separators, of which the following is a specification.

It has been found that the great obstacles in the way of successful and rapid work with machines of this kind have been, first, in the formation of circulatory currents within the mass of milk that tend to prevent the separa-- not only obstructs the passage of the cream' particles to the center, but clogs the passages and prevents perfect circulation, as Well as causing waste of cream.

Figure 1 represents a section of a separatorbowl and an elevation of a milk quieting or steadying device of this invention in position in the bowl. Fig. 2 is a horizontal section of the gravity-piece composed of solid prismatic sectors or bars and end rings and of the core. Fig. 3 is a cross section of the bowl and quieting-device, the section planes being indicated Figs. 4 and 5 are sections of the sectors, bars, or prisms of the gravity-piece, somewhat modified. Fig. 6 is a modified elevation of one of the sectors or prisms of the gravity-piece for a bowl with conical top or bottom. Fig. 7 is a perspective of cream-steadying core such as may be used when milk is admitted at the top and drawn from the bottom of the bowl. spective of core which may be used for a bowl to which milk is admitted at bottom and drawn from the top; Figs. 4 to 8 are on relatively larger scale than Figs. 1, 2, and 3.

It will be understood that as the invention relates only to milk-quieting devices and not to the separator-bowl no attempt has been made to illustrate particular constructions of such bowls, it being apparent that the improvement may be applied to any such bowl to which it is adapted.

Fig. 8 is a per- -The numeral 1 indicates a separator-bowl of-common construction. be used.

2 indicates the gravity quieting or steadying' device. This is preferably a metallic piece consisting of horizontal end rings 4. 4, which are connected by vertical prisms or sectors 3 3, the prisms or sectors being rigid with the rings and having spaces 5 5 between Other forms might them. The gravity-piece is of such diameter tube '7, although, as in Fig. 7, this tubemay be replaced by a ring 7 A separating-plate 8 extends horizontally part way across the milk pool. The milk is fed to the bowl through the tube 7 or in other usual manner, and the cream and blue milk are withdrawn in any manner common in this art.

The oream-steadying core is not of my in Vention, being well known in this art. Its use with the gravity device 2 seems to be novel. The vanes of the core extend from the tube 7 'to close proximity with the prisms or sectors of the gravity-piece 2.

The gravity-piece 2, composed, as it is, of solid prisms with narrow channels between,

serves to break up the liquid column in the bowl into comparatively small vertical columns, and the separation of the milk from the cream is much more readily effected. The solid sectors or prisms displace a quantity of 'milk or cream in the bowl equal to their cubic contents. The piece 2, having all the prisms 3, is readily attachable as one piece and can be conveniently cleaned and replaced, as can the core-piece. Preferably opposite wings of the core-piece may extend slightly into the spaces 5 between the sectors 3 to prevent separate rotation of the gravity-piece and core.

What I claim is- 1. In a centrifugal machine,the milk-quieting device consisting essentially of the two flat rings connected by solid vertical bars, there being narrow vertical spaces or passages extending radially between said sectors, substantially as described.

2. The combination with the separatorbowl having supports as 10 on the bottom, of the piece consisting of end rings one of which rests on said supports, and solid vertical bars connecting said rings, substantially as described.

3. The combination with a separator-bowl of a quieting device consisting essentially of a supporting-ring and solid bars extending vertically from the same, leaving narrow Vertical passages between said bars, said passages extending radially to the bowl and sepa-
